Agile is a software development methodology to build a software incrementally using short
iterations of 1 to 4 weeks so that the development process is aligned with the changing
business needs. Instead of a single-pass development of 6 to 18 months where all the
requirements and risks are predicted upfront, Agile adopts a process of frequent feedback
where a workable product is delivered after 1 to 4-week iteration.
RolesinAgile
ScrumMaster
A Scrum Master is a team leader and facilitator who helps the team members to follow agile
practices so that they can meet their commitments. The responsibilities of a scrum master
are as follows:
To enable close co-operation between all roles and functions.
To remove any blocks.
To shield the team from any disturbances.

To work with the organization to track the progress and processes of the company.
To ensure that Agile Inspect & Adapt processes are leveraged properly which includes
o Daily stand-ups,
o Planned meetings,
o Demo,
o Review,
o Retrospective Meetings, and
o To facilitate team meetings and decision-making process.
ProductOwner
A Product Owner is the one who drives the product from business perspective. The
responsibilities or a Product Owner are as follows:
To define the requirements and prioritize their values.
To determine the release date and contents.
To take an active role in iteration planning and release planning meetings.
To ensure that team is working on the most valued requirement.
To represent the voice of the customer.
To accept the user stories that meet the definition of done and defined acceptance
criteria.
Cross-functionalTeam
Every agile team should be a self-sufficient team with 5 to 9 team members and an average
experience ranging from of 6 to 10 years. Typically, an agile team comprises of 3 to 4
developers, 1 tester, 1 technical lead, 1 product owner and 1 scrum master.

Product Owner and Scrum master are considered to be a part of Team Interface, whereas
other members are part of Technical Interface.
HowanAgileTeamPlansitsWork?
An Agile team works in iterations to deliver user stories where each iteration is of 10 to 15
days. Each user story is planned based on its backlog prioritization and size. The team uses
its capacity − how many hours are available with team to work on tasks − to decide how
much scope they have to plan.
Point
A Point defines how much a team can commit. A point usually refers to 8 hours. Each story is
estimated in points.
Capacity
Capacity defines how much an individual can commit. Capacity is estimated in hours.

WhatisaUserStory?
A user story is a requirement which defines what is required by the user as functionality. A
user story can be in two forms:
As a <User Role> I want <Functionality> so that <Business Value>
In order to <Business value> as a <User Role> I want <Functionality>
During release planning, a rough estimate is given to a user story using relative scale as
points. During iteration planning, the story is broken down into tasks.
RelationshipofUserStoriesandTasks
User story talks about what is to be done. It defines what a user needs.
Task talks about how it is to be done. It defines how a functionality is to be
implemented.
Stories are implemented by tasks. Each story is a collection of tasks.
User story is divided into tasks when it is planned in current iteration.
Tasks are estimated in hours, typically from 2 to 12 hours.
